In President Trump’s address to Congress, he cited a National Academies report on the economic consequences of immigration. The report found that the long-term impact of immigration on the wages and employment of native-born workers overall is very small, and that any negative impacts are most likely to be found for prior immigrants or native-born high school dropouts. First-generation immigrants are more costly to governments than are the native-born, but the second generation are among the strongest fiscal and economic contributors in the U.S. The report concludes that immigration has an overall positive impact on long-run economic growth in the U.S. Another National Academies report found that immigrants and their descendants integrate into American society over time, for example, in the areas of educational attainment, occupations, and health.
